IMPROVEMENT IN RAIN-WATER CUT-OFFS.

Specificationforming part of Letters Patent No. 55,072, dated May 29,1866.

To all whom it may concern:

Be it known that I, L. W. DOTY, of Aurora, in the county of Kane andState of Illinois, have invented a new and Improved Gut-Oft' forRain-I/Vater Pipes 5 and I do hereby declare that the followingl is ai'ull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had totheaccompan ying drawings, forming a part of this specification, inwhich- Figure l is a longitudinal vertical section of my invention,taken on the plane of the line ma', Fig. 2. Fig. 2 is also alongitudinal vertical section, taken on the plane of the line y y, Fig.l.

Similar letters ot' reference indicate like parts.

My invention consists in the construction ot' a box, ot' metal or anyother suit-able material, having a partition extending up for a certaindistance from its base, at the top of which there is pivoted or hinged aswinging gate so arranged in regard to an induction-pipe opening intothe top of the box that the water entering the box may be thrown intoeither one of two ed uct-ion-pipes emanating from the bottom of the saidbox.

To enable others to understand my invention, I will proceed to describeit.

A designates a box, which is made of any suitable metal or material, andot' any appropriate shape. An induction-pipe, B, opens into the top ot'this box, and two eductionpipes, C C', lead out from the bottom thereof,one being arranged on each side ofthe box.

D is a partition-Wall extending longitudinally from the bottom ot' thebox, between the two pipes C C', up a certain distance, according to thelength of the box.v In the present instance it extends about half thelength of the box. This wall'divides the lower part of the box intoseparate longitudinal chambers, one situated over the eduction-pipe Cand the other over the eduction-pipe C. An eye, a, or any'other suitablemeans, is employed at the top of this partition/for receiving andpermitting to revolve a shaft, I), one end of which projects out beyondthe face or front wall of the box, and has a knob, c, secured to it bywhich to revolve it. To this rod or shaft b a gate, E, is secured. It isarranged to swing from one side to the other ot' the box, and its Lipperend lies close against the sides of the box A, near to the end ot' theinduction-pipe from the exterior to the interior of the box,-

are arranged so as to hold the gateE securely against that side ot thebox against which its upper end may be thrown in order to cause thewater coming through the induction-pipe to pass down to that one of theeductionv-pipes C C', through which it is intended to conduct it. Aglance at the drawings willv show that by adjusting the gate E so as tobear against either one or the other side of the box A the water may allbe caused to pass through either one or theother ot` the eduction-pipesG C.

The box A is intended to be secured to the side of the building orwherever the rain-water conducting-pipe is located. This cut-oit' willbe ot' great service in many cases-for instance, in large cities, wherepersons living in the upper stories of houses above the head ot' theartilicially-introduced water, or where such artificially -introducedwater would be unfit for washing purposes, may, by the use of thiscut-oit thrown into any receptacle therefor, such as a tank or barrel,the desired quantityof water, and when this is obtained by readjustingthe cut-off the water from the roof of the building will be permitted topass through the usual conducting-pipe. Again, most, it' not all, of theimpurities in eisterns are brought there with the water directly fromthe root' ot' the houses, where the said impurities, such as dirt andsome of the heavier products of combustion passing out ot' the chimney,have collected. A fall of rain is sure to carry them all down iutoacistern. Now, by the use of this cut-oit' the first flow of the watercan be caused to pass through a wastepipe until the water be clear, whenby adjusting the cut-oft the pure water can be allowed to how into thecistern.

What I claim as new, and desire to secure by Letters Patent, is

rlhe gate E and spring d, in combination with the partition D, arrangedrelatively with the induction-pipe B and eduction-pipes C O.
